' LUZBBICATING DEVICE.

v Specification of Letters Patent.

Application filed May 23, 1910. Serial No. 562,905. 1

Patented Dec. 17, 1912.

a machine with oil without spilling the oil,

such devices being applicable for lubricating ring spindles used in cotton spinning, but can be used for other purposes also.

The invention is of that kind wherein there is a can or container having a spout or nozzle projecting therefrom, the can being fitted with a pump for obtaining a forced feed, and with means whereby a quantity of oil is discharged through'the spout at each stroke.

The invention will be understood from the following description, reference being had to the accompanying drawings, in which, 1

Figure 1' is a sectional view'of my lubrieating device, with the piston in the position it will occupy when the knob Y is pressed down by the hand; Fig. 2, a front view; Fig. 3, a detail sectional view showing a slight modification and Fig. 4 is a detail view showing a portion of the structure of Fig. 1 in top plan.

In carrying the invention into'eflect, I solder or otherwise, fasten to the can A in front at or near the base, a block or valvecasing B, which projects through the can to the inside, and is there provided with a cupshaped part G, into which the lower end of the pump. barrel is screwed or otherwise secured. Passing through this member from the cup or pump barrel is a passage D, closed at the front end by a removable plug E, and below this passage is another similar passage F, which gives access to the interior of the container A. This passage is also closed by a removable plug G at the front. These removable plugs provide means for cleaningthe two passages D and F.

lntersecting the upper passage D and joining the lower one F is a vertical conduit J, formed at its intersection with the horizontal passage F with a valve seat H, which contains a vertical lift ball valve I,

upper oil passage D when the pump barrel is filling by suction. The stop N may be serrated- The tubular member K receives at the top a flanged nipple O to which is secured a spout P projecting upward to the top of the container, and as this nipple is held concentric in member K the spout is has been removed for cleaning. The pro-- jecting arm Q aforesaid is provided at the end with a guide piece R, to hold the device with the bent down or discharge end of the spout in pro er position above the foot-step socket or ot er part requiring to be filled with oil, and thus avoid spilling. This guide piece embodies projecting arms with a V- groove, which abut against the outside of the part requiring to be filled with oil. The lower end of the nipple O is madeto form a stop m serrated at bottom.

The casing B whi h is soldered to the front of the container A, is by preference curved at front, to the radius of the container; but may be made of circular or other form, or the container-might have the front flattened at the place where the member B goes throu h. The faces at the top of the members and K can be provided with washers S of leather or other compressible material to make good the joints. The members K and O are made to fit properly so that their flanges may easily come together, and when brought together they are locked by screws T passed through them, and screwed into holes in the flange b of the casing B.

By this invention the use of springs for keeping the valves normally on their seats is entirely dispensed with, these springs being found to be a constant source of trouble. The piston V of the pump W is provided or formed with annular'circumferential grooves X, which when the apparatus is in use are filled or occupied by oil, which acts as a packing.

The mode of action is as follows :The device is so placed that the guide piece R. abuts against the outside of the part requiring lubrication, and holds the spout in proper relation therewith, also with the spout a little out of or slightly dipping into it, but not enough to catch therein. I then place the thumb on the knob Y of the piston rod and. depress it so that the piston is forced from the top to the bottom of its barrelW, that is, into the position shown in Fig. 1. This squirts,a quantity of oil directly through the upper oil passage D, lifts the upper valve M (the lower one I being closed), and so through the spout P directly into the part requiring lubrication, in such mannerthat none is spilled. By releasing the knob Y the piston springs upward by a spring Z, closing the outlet valve M and drawing in by suctlon a fresh quantity of oil through the lower valve I and lower passage F from the container A into the pump barrel W ready for the next operation. The piston in its normal position is held in its upper position by the sprin Z. Should any of the oil passages or va ves get choked, all that is necessary is to remove the plugs E and vGr at the end of the passages, or lift out the upper nipple O with its spout P, and the tubular member K with its valve M. The parts can then be readily cleaned. The parts can be readily replaced, and the members K and 0 form a centering for the spout. The pump is contained wholly within the container A, and the container requires no base flange below its bottom or floor. The spout P need not necessarily project upward to the top of the container. Any suitable valves other than the ball valves may be used.

I do not confine myself to a casing B made exactly as in Figs. 1 and 2. For example, it could be made with a circular boring with the passages D and F leading thereto as in Fig. 3, from the pump barrel and container respectively, and into the said boring is screwed or otherwise secured, a plug 10 containin the vertical conduit J, which has provi ed therein the, valve seats H and L and the valves I and M, also a con-' tinuation of the passages D and The mode of operation is the same as that already described. For cleaning purposes, the plug may be removed from the boring in the chamber B by unscrewing it by means of the head J This arrangement comes within the scope of my invention.

I am aware that oil cans have heretofore been made with valve chambers, to which ball gravity valves have been fitted, but in that case the valve chamber was inside the can and the valves could not be readily withdrawn for cleaning or repair. Also that in sight feed lubricators each pump with its plunger, spring and non-return valves has been formed in one casting, which is secured-in place by set screws, and removable plugs were provided at the ends of the horizontal valve passages in the casting. Thus any one feed pump and its parts may be withdrawn for cleaning or repair, but in that case the valve chamber was not in connection with the reservoir, but in connection with a sight or pipe feed passage and the whole casting which was outside the reservoir with its pump valves and springs were removable collectively, and the eneral arrangement of parts was quite di erent from mine.

I declare that what I claim is 1. In a lubricating device, a vessel, a valve casing projecting through one of the walls thereof and communicating with the interior near the bottom, a pump connected with the valve casin and located within the vessel, said casing eing provided with a passage opening into the vessel, and a passage connected withthe pump, each of said passages communicating with the exterior of the casing, valves for controlling the passage of liquid through the casing and means for closingtheouter ends of said passages.

2. In a lubricating device, a vessel, a valve casing projecting through one wall thereof and having a passage connected with the interior of the vessel, a pump connected with the interior of the casing, a spout connected with'the casing, and a guard member secured to the vessel adjacent to the end of the s out for contacting with the article to be In ricated. v

3. In a lubricating device, a vessel, a casing projecting through the wall thereof, said caslng being provided with a passage connecting with the interior of the vessel and with the outer portion of the casing, means for closing the outer end of the passage, a pump connected with the casing, a tubular member located within a bore in the casing and having communication with said tacle and having connection with the valve casing, said casmg being provided .with a bore, .a tubular member located within the bore, the casin having a passagefor connecting said tu ular member with the interior of the vessel, a valve for controlling the passage of liquid through the casing from the receptacle into the tubular member, a nipple connected with the tubular member and a spout connected with the nipple;

5. A lubricating device comprising a re ceptacle, a casing projecting through one wall thereof, said casing being provided with a passage connecting with the interior of the receptacle, a second passage adjacent to the passage first mentioned, a pump within the receptacle having connection with the second passage, said casing also being provided with a bore having connection with each of the aforesaid passages, valves for controlling the flow of liquid from each of thepassages to the said bore, a tubular member located within the bore and a spout co1nmunicating with the tubular member.

In witness whereof, I have hereunto signed my name this 14th day of May 1910, in the presence of two subscribing witnesses.
